It will of course pool when the engine is not running, but while the engine is running all the oil is churning around.
That way the oil supply is still adequate even during aerobatics.

Most modern petrol aero engines use fuel injection. There was a problem during WWII where older Spitfires would cut out during a roll to the left. The fuel was fed to a normal carburetor and the supply in the float chamber would be flung to the side due to centrifugal force and miss the bottom of the jet tube.
The German pilots knew this (they had fuel injection from the start) and tried to get our boys to roll over to port.
